Rule aws_route_not_specified_target seems to be not working properly

Hi,

we have the following code:

...
resource "aws_route" "private_tgw_egress" {
  count = var.enable_nat_gateway == false && var.enable_transit_egress == true ? local.private_subnet_count : 0

  route_table_id         = element(aws_route_table.private.*.id, count.index)
  destination_cidr_block = "0.0.0.0/0"
  transit_gateway_id     = var.transit_gateway_id

  timeouts {
    create = "5m"
  }

  depends_on = [aws_ec2_transit_gateway_vpc_attachment.this]
}
...

This result in the following error:

1 issue(s) found:

Error: The routing target is not specified, each aws_route must contain either egress_only_gateway_id, gateway_id, instance_id, nat_gateway_id, network_interface_id, transit_gateway_id, vpc_peering_connection_id or vpc_endpoint_id. (aws_route_not_specified_target)

I think this is wrong because the parameter _transit_gatewayid is specified:

I tried running tflint from VScode or shell but this does not change anything.

Version

Example:

$ tflint --version
TFLint version 0.29.1
+ ruleset.aws (0.4.1-bundled)
$ terraform version
Terraform v1.0.1
